You have raised one of the most interesting subjects in the detective work of genealogy: the reliability of sources. Source reliability often comes in many shades of grey, rather than black or white.
IMHO the best way to begin to approach this is from a standard scholarly research viewpoint, which requires that information be substantiated by primary and secondary sources.
If you think like this, you will soon understand – if you don't already – that even primary sources may include "dodgy" information. Death certificates, for instance, are primary sources, but often contain inaccurate information provided posthumously by informants.
So how to reduce (you will never eliminate) "dodginess"? The ideal may be compared with triangulation: a technique of deriving a navigational fix, or finding submerged submarines, from three or more different bearings. The more non-self-referencing primary sources you can find for any information, the more reliable that information should be.
Even potentially dodgy sources – a genealogy with no source documentation, for example, or an IGI entry – are best recorded in Reunion as sources, with everything known about their authorship. The nature and number of sources then speak for themselves about reliability and "non-dodginess". Reunion research notes can be used to record work on lines of inquiry, reasons for doubt or confidence in information, and need for further research.
The Harvard Guide to Using Sources at http://isites.harvard.edu/icb/icb.do...tabgroup106846 is a good guide to general scholarly and academic principles of using sources.
Hertfordshire Genealogy has a good discussion of "Sources and Reliability" in the genealogical context at http://www.hertfordshire-genealogy.c...52-sources.htm
Eliminating dodgy information from genealogy is almost unattainable, but pursuit of that ideal is among the most fun of this hobby.
Have fun!
